i am facing a starnge issue. My wireless works all of fine with MS IAS as radius server dot1x authenstication. But the problem comes when i add an interface on controller from vlan 1 (i.e.same of where my Radius server exist) After this interface is created all of my dot1x wireless setup stops working for all. And also does not work for the new interface vlan 1 network also. My servers and users wired network is on vlan 1.
Your show-run is not complete so it is hard to see your interface/vlans you are using. Have you checked STP? If your wireless network is on the same vlan as your wired you potentially can run into a loop issue.
